James White said he believes there is no pressure on him today, even though he has an audience with the King.

The Knicks’ relatively unknown swingman will be assigned to defend LeBron James at the beginning of this afternoon’s matinee against the Heat at the Garden. Coach Mike Woodson said yesterday White will start at small forward for the second straight game, setting up the James vs. James battle.

“To me, I go into it, you’re playing against an All-Star or people say he’s the best player in the game. I have nothing to lose,” White said. “I just go out there and just leave it all on the court. Just work hard and fight.”

White will not be guarding James all afternoon. Even after joining the starting lineup on Friday in Washington (replacing Jason Kidd), White played just a little more than 10 minutes.

So the Knicks will have other people assigned to slow down the Heat superstar, including Iman Shumpert (who figures to start on Dwyane Wade), Carmelo Anthony and perhaps J.R. Smith. Even Kenyon Martin could get possessions against James.

The 6-foot-7 215-pound White did guard the 6-foot-8 250-pound James at times in the Knicks’ 112-92 rout over the Heat on Dec. 6, logging almost 17 minutes that game (though Anthony and Shumpert were out). James was still effective — the three-time MVP poured in 31 points on 11-for-20 shooting, along with 10 rebounds and nine assists.

Nevertheless, Woodson said he was happy with White’s performance in that game.

“I thought [White] played pretty well,” Woodson said. “He made a few shots. Defensively, he wasn’t too bad. I think he’s athletic enough and rangy enough to stay with those guys, but they’re a load for anybody. I don’t care who you are. Wade and LeBron right now are playing as well as anybody in the league.”

James just wrapped up a February in which he averaged 29.7 points, 7.8 assists and 7.5 rebounds while shooting 64.1 percent from the field. He shot just 4-for-14 in the Heat’s 98-91 win over Memphis on Friday.

White, whose team is 5-2 when he starts this year, said he doesn’t need to watch any tape of James.

“I’ve seen enough,” he said. “I’ve seen enough of him in my life to know. Everybody has.”They play all the time on TV and just seeing him play over the years, I’ve pretty much seen enough of him.”
